-      Retrieve a file in binary transfer mode.  *cmd* should be an appropriate
-      ``RETR`` command: ``'RETR filename'``. The *callback* function is called for
-      each block of data received, with a single bytes argument giving the data
-      block. The optional *blocksize* argument specifies the maximum chunk size to
-      read on the low-level socket object created to do the actual transfer (which
-      will also be the largest size of the data blocks passed to *callback*).  A
-      reasonable default is chosen. *rest* means the same thing as in the
-      :meth:`transfercmd` method.
